This patchset is related to remove the MMC_DATA_STREAM.
It's not set to MMC_DATS_STREAM anywhere.
This flag had been used with CDM11 and CMD20.
But CMD11/CMD20 have become obsolete.
To reduce the confusion, removed the unnecessary flag.
Jaehoon Chung (11):

It's not set to MMC_DATA_STREAM anywhere.
It seems that it had been used with CMD11/CMD20.
But according to Spec, CMD11/CMD20 are obsolete command.

After removed the MMC_DATA_STREAM, only two flags are remained.
(MMC_DATA_READ and MMC_DATA_WRITE)
The flags of READ and WRITE can't be used together.
That's why it doesn't need to use "OR' operation.

This patchset is related to remove the MMC_DATA_STREAM.
It's not set to MMC_DATS_STREAM anywhere.
This flag had been used with CDM11 and CMD20.
But CMD11/CMD20 have become obsolete.
To reduce the confusion, removed the unnecessary flag.
